Entychites
From BiblePortal Wikipedia
Entychites [1]
a sect of the followers of Simon, who, according to Clemens Alex. (Stromatavii, 17; page 900), derived this name from their promiscuous ( Ἐντυγχάνω ,) sexual intercourse at the night meetings. Others write the name Eutychites or Euchites. Envy was always reckoned an odious sin, and one of the first magnitude; but there are no distinct penalties attached to it, inasmuch as, before it could bring a man under public discipline, it required to be displayed in some outward and vicious action, which received its appropriate punishment.
